Here is a quick idea. A lot of players are a little bummed because they have their perfect Level 50 anointed gun and they are worried that they will never get it again in 53 or future caps.
How about a system where you can gain gear upgrade points and once you have enough you can spend them on leveling up a piece of gear in you backpack? Make not too easy so that there is still a big challenge to get enough points.
Anyone like this idea?
